Hi, this weekend my son-in-law and I shot many hundreds of rounds using 38 Short & Long Colt heeled ammo. It's easy to understand why the government decided to go with internally lubed bullets starting with the 38 Long Colt. The outside lubed heeled bullets are dirty and gums up the cylinder chambers after a lot of shooting. Using the internally lubed hollow based wadcutters in 38 Special provides very clean shooting where one wouldn't know that many hundred rounds have been fired. The hollow based bullets are accurate enough for casual target shooting.
I'm done loading any more heeled bullets, never again.
Regards,
Richard
